(quantum mechanics)

Quantum-mechanical device in which one selects the common eigenfunctions of a complete set of quantum-mechanical operators as a basis of vectors in a Hilbert space, and expresses wave functions and operators in terms of column matrices and square matrices, respectively, which correspond to this basis.

Berkovich, Kazarin, and Zhmud' introduce character theory and its applications in the representation theory of finite groups to people with a comparatively modest mathematical background, exceeding the usual algebra course only with a knowledge of finite groups, even if a superficial knowledge.

16) Therefore, unveiling the subjective dimension, using the Social Representation Theory, allows to recognize and value the cognitive aspect of the individual, according to this perspective interferes in social practices, attitudes, and behaviors related to the representation object.

In line with the social representation theory (SRT; Moscovici, 1961, 2008), and the central core theory (CCT; Abric, 1993, 2001; Rateau, Moliner, Guimelli & Abric, 2011), the hypothesis that the emotional unconscious context changes will differentially affect the elements of the SR function to their structural status (central vs.
